Systems and methods of using implanted or wearable micro electronic devices and for using a mobile device to communicate with and manage such micro electronic devices

1. A method of communicating information between a Radio Frequency (RF) microdevice and a mobile device, comprising steps: A. providing the RF microdevice consisting of (i) a housing, (ii) an antenna disposed inside the housing, (iii) a microprocessor disposed inside the housing and communicatively connected to the antenna, and (iv) a tuning capacitor disposed inside the housing and communicatively connected to the microprocessor; B. attaching, subcutaneously, the RF microdevice to a user; C. providing the mobile device, including: i. at least one RF transmitter, and ii. at least one processor communicatively connected to the at least one RF transmitter, iii. a graphical user interface connected to the at least one processor, iv. a power supply connected to at least one processor, and; v. at least one powered service element, the at least one powered service element being selected from a group consisting of a wireless local area network (WLAN) antenna, a cellular network antenna, a clock, a camera, a lamp, an inclinometer, a gyroscope, a speaker, a microphone, a subscriber identification module (SIM) port, an external audio port, and a power charge port, and D. the user brings the RF microdevice near the mobile device RF transmitter, whereby: i. the RF transmitter of the mobile device communicates with the RF microdevice via RF signals, and ii. the RF microdevice transmits information to or receives information from the at least one powered service element.
